No. 18638.—18th October, 1904.—FRANCIS ARTHUR RICH,
of Remuera, near Auckland, New Zealand, Mining Engineer
(nominee of Samuel B. Christy, of Berkeley, Alameda, Cali-
fornia, United States of America). Improvements in the
recovery of gold and silver from cyanide ore-extraction solu-
tions.

Extracts from Specification.—There are two great difficulties
in the recovery of gold and silver from such dilute solutions.
The first lies in their extreme dilution. . . . The
second lies in the fact, not generally known, that the elec-
tric current acts differently on metallic cyanides than it does
on other metallic compounds in solution. . . . The
method by which I have been able to overcome this diffi-
culty by directly attacking it has been, after clarifying from
sediment by filtration or settling the solution to be treated,
to collect it in a large storage-tank or reservoir, and then to
circulate it through a suitable electro-chemical cell, and
back again to the storage-tank rapidly and repeatedly, in
such a manner that the solution is brought into intimate
contact with anodes and cathodes in rapid alternation, until
the gold and silver content has been sufficiently reduced.
By my improved process I have been able to handle such
solution at a rate corresponding to 1,000 tons a day in a
deposition-box of only 30 cubic feet, and have secured
better precipitation than has ever before been obtained
with a deposition-box holding 6,000 cubic feet. When the
solution is free from sediment, and the ore leaches rapidly
enough, instead of collecting it in a storage-tank, I may use
the ore-extraction tank as a storage-tank, pumping the
solution from below the filter and returning it on top of
the ore.

No. 18642.—21st October, 1904.—ALEXANDER ROSS and
WILLIAM ROSS, both of Napier, New Zealand, Rope and
Twine Manufacturers. An improved binder-twine.

Claims.—(1.) The improved method of manufacturing
binder-twine, the same consisting essentially in first forming
a core of any desired material, and then spinning upon such
core a wrapping of suitable fibre, substantially as specified.
(2.) The improved method of manufacturing binder-twine,
the same consisting essentially in forming a core of flax tow
and then spinning upon such core a wrapping of flax or
hemp fibre, substantially as specified.

No. 18647.—22nd October, 1904.—GLOBE PROPRIETARY
COMPANY, LIMITED, a registered company carrying on busi-
ness in Auckland, New Zealand (assignees of Ernest Herbert
Littlejohn, of Auckland aforesaid, Manager of the said com-
pany, the assignee of William H. Morehouse, of Wasco,
Oregon, United States of America). An improved hammock-
support.

Claims.—(1.) For the purpose indicated, a pair of
stretcher-bars adapted to support a hammock between
them, each of said bars being fixed to a rocking-bar at its
lower end, the rocking-bars being connected by a longi-
tudinal beam, with means for maintaining the stretcher-

bars in position with the hammock between them, substan-
tially as specified and illustrated. (2.) For the purpose
indicated, in combination, a longitudinal main beam, cross-
beams secured to the main beam, brackets one at each end
of each cross-beam, an eye formed upon each bracket above
the cross-beam, rocking-bars journalled in said eyes, a
stretcher-bar fixed in each rocking-bar, hooks carried in eyes
upon the main beam, said hooks being adapted to take into
one or other of a plurality of holes formed in the stretcher-
bar, diagonal stay-bars between the cross-beam and the
main beam, and stay-bars between each stretcher and the
rocking-bar to which it is connected, substantially as speci-
fied and illustrated. (3.) In apparatus for the purpose indi-
cated, a bracket designed to carry the end of a cross-beam,
said bracket being splayed outwardly at its lower end to form
a support, and having an eye at its upper end to form a
journal for a rocking-bar, substantially as specified and
illustrated. (4.) Apparatus for the purpose indicated, con-
sisting of the parts arranged, combined, and operating sub-
stantially as and for the purposes specified, and as illustrated
in the drawing.

No. 18648.—22nd October, 1904.—JOHN JULIA RIDGWAY,
of Rosebank, Staten Island, New York, United States of
America, Mechanical Engineer. Improvements in belt-
conveyers.

Extract from Specification.—This invention relates to
improvements in belt-conveyers of the type that consist in
endless belts mounted on rollers and caused to travel by the
rotation of the rollers in order to carry articles or materials
fed on to them from one place to another. The improve-
ments consist in the provision of means whereby the con-
veyer-belt may be caused to assume a curved or trough form
in cross-section while travelling along the distance through
which the article or materials have to be conveyed. Such
means consist broadly in the employment of a duplicate
endless belt mounted between the main conveyer-belt so as
to travel along in parallel lines thereto. To the outer face
of this second belt are attached, at regular intervals apart,
transverse battens or members that are curved downwards
and inwards from both ends towards their middle. When
the belts are drawn taut these battens will press against the
under-face of the outer or main conveyer-belt so as to cause
it to assume the same trough-like form as the battens.
Special means are provided whereby both of the belts may
be caused to travel simultaneously at the same speed, may
be regulated in tension independently of each other, and
whereby the outer belt may have its edges turned upwards
before it comes under the influence of the trough-shaped
members.

No. 18651.—20th October, 1904.—JOHN ANDERSON, of
Dunedin, New Zealand, Brassfounder. Improved auto-
matic-pressure appliance for cheese-presses.

Claims.—(1.) In cheese-presses where the pressure is given
by screw or suchlike, the method of pressing against a block
engaging compound levers and weights so that the required
pressure is given to the cheese and when the weights are
pressed up said weights continue to maintain the same
pressure till the end of their stroke, upon the cheese, all
substantially as set forth, and as illustrated in the drawing.
(2.) In cheese-presses, the pressure-resistance block in com-
bination with a system of levers and weights for preventing
overpressure and continuing the pressure to the end of the
stroke of the weights and levers, on said cheeses, all substan-
tially as set forth, and as illustrated in the drawing.

No. 18654.—25th October, 1904.—JOHN WILLIAM WRIG-
LEY, of Rotorua, New Zealand, Architect. An improved
method of fixing the sheets of corrugated and other iron
roofing.

Extract from Specification.—This invention relates to an
improved method of arranging and fixing the sheets of
corrugated iron and other sheet-iron roofing, and it has been
designed in order to provide for the collection of the con-
densed moisture upon the under-surface of the roofing, and for
its delivery on to the outside thereof. The dripping of the water
caused by such condensation into the building is thus pre-
vented. The invention consists in so lapping the sheets that
the top end of the lower sheet of each lap shall be a short
distance from the under-surface of the lower end of the upper
sheet. Waters of condensation thus running down the
